B-Chain Alignment
Equalization facilities for the subwoofer
channel are also different than for the
other channels.
The subwoofer equalizer is a digital cut-
only filter, with adjustable frequency, Q
(or sharpness), and amount of cut. From
the analyzer display, determine the
primary low-frequency resonant peak of
the room and adjust the
Frequency
,
Q
,
and
Cut
controls to cancel this
resonance. The front panel knob and
"Up/down arrow" key (SK4) are once
again used to select and move the
controls.

Now that the equalization is complete,
the sound pressure level in the room can
be set exactly. Return to the output level
adjust window by pressing

then the

key (SK2).
Since the system was calibrated earlier, it
is not required to perform the calibration
again, however it is prudent to recalibrate
if microphone placement has changed.
Press

to recalibrate, or
CANCEL
to
use the earlier calibration data.
